the relations of abbasid state and bizans empire were more hostile in rashid era. on the other hand, the good understanding of abbasid and westerns was one of the most important reasons of this hostility because they were very frightened of their cooperation and this factor continued until mamun era. great sharlman succeeded his father, pepin, and in this era, his relation with ghostantaniyyeh ...

With the beginning of the 19th century, England entered into a transitional period. Sociologists believe that in each era of transformation, the ruling class tries to establish its own values, but some resistance to these new values is inevitable. Thomas Hardy's novels in general, and Under the Greenwood Tree specifically, are no exception. Based on these notions, this paper tries to interpret ...

Bending of purple membranes in dependence on the pH analyzed by AFM and single molecule force spectroscopy R.-P. Baumann, M. Schranz and N. Hampp, Phys. Chem. Chem.

We have expressed recombinant RNase P protein from Escherichia coli in high yield. A hexahistidine sequence at the amino terminus allowed protein purification in a single step. Mass spectrometry confirmed the molecular weight of the purified protein and indicated a purity of > 95%. Protein functionality was demonstrated by reconstitution of active holoenzyme.

Site-specific fluorescent labeling of proteins in vivo remains one of the most powerful techniques for imaging complex processes in live cells. Although fluorescent proteins in many colors are useful tools for tracking expression and localization of fusion proteins in cells, these relatively large tags (>220 aa) can perturb protein folding, trafficking and function. Much smaller genetically enc...

BACKGROUND Making peptide pharmaceuticals involves challenging processes where many barriers, which include production and manufacture, need to be overcome. A non common but interesting research area is related to peptides with intracellular targets, which opens up new possibilities, allowing the modulation of processes occurring within the cell or interference with signaling pathways. However,...

Recombinant clathrin protein fragments form assemblies that template gold nanocrystals in an array across the latticed surface. The nanocrystals exhibit unusual anisotropic morphologies with long range ordering, both of which are dependent upon the presence of a hexahistidine tag on the clathrin heavy chain fragments.

the notion of peace, regardless of theorizations accepted in th field and since the                  enlightenment period, and the era known as modernism, has, constantly, been one of the challenges of mankind, and also scientists in the field of political sciences and international relations.  contrary to the presentation of the idea of peace and respect to the human rights in some of the fore...
